# Checkbox

[Checkboxes](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox) allow the user to select multiple options from a set. If you have multiple options appearing in a list, you can preserve space by using checkboxes instead of on/off switches. If you have a single option, avoid using a checkbox and use an on/off switch instead.

<!-- example -->
```jsx
import Checkbox from 'react-toolbox/checkbox';

const TestCheckbox = () => (
  <div>
    <Checkbox label="Checked option" checked />
    <Checkbox label="Unchecked option" />
    <Checkbox label="Disabled checkbox" checked disabled />
  </div>
);
```
